How The Pawns Move :-

At the beginning of the game, white's pawns are lined up on the second rank, and black's are on the seventh:

From this position, you can chose to move any pawn one or two squares forward:

After they leave their initial position, pawns are restricted to moving directly forward one square at a time. If the square immediately in front of a pawn is occupied by another piece, then the pawn cannot move:

The pawn on the left can move forward to the white square directly ahead of it. The one on the right can't.

Pawns are the only pieces that move differently than normal when they capture. Pawns capture by moving one square diagonally forward, and not by moving straight ahead:

The pawn can capture the knight or bishop, but not the rook.
